ONE OVERTON PARK IN ATLANTA ACHIEVES LEED GOLD CERTIFICATION

(ATLANTA) – The Atlanta office of Hines, the international real estate firm, announced today that One Overton Park received Gold certification in the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED®) Green Building Rating System. The property was certified in the Existing Buildings: Operations & Maintenance program.

One Overton Park is a 15-story 387,267-square-foot multi-tenant office building that is managed and leased by Hines.

Hines developed the Pickard Chilton-designed building in 2002, and in 2006 the building was acquired by a wholly owned subsidiary of Franklin Street Properties Corp. (NYSE AMEX: FSP) (“FSP”).

Hines Senior Vice President Kurt Hartman said, “As Hines’ second LEED Gold certified property in Atlanta, our development and operating teams have demonstrated a mastery of the LEED process.

One Overton Park provides an excellent example of how Hines partners with asset and portfolio owners to create and preserve value while benefitting the environment.”

FSP Vice President Toby Daley added, “One Overton Park is the first building in our portfolio to achieve certification since FSP launched its LEED initiative.

The fact that One Overton Park attained Gold certification in such a relatively short period of time is a tribute to the efficient design of the building and the skill of Hines’ property management staff and engineering services.”

One Overton Park has earned the U.S. Environmental Protection Agency’s ENERGY STAR® three times since 2006 and has a current score of 93.

The building consumes 47 percent less energy and emits 47 percent fewer emissions than the average U.S. building.

This translates to estimated annual energy cost savings of $1.46 per square foot.

Resulting projected annual greenhouse gas reductions are equivalent to removing from the road more than half of the 1,400 cars that fit into One Overton Park’s parking garage.

Green features include a comprehensive green cleaning program, sustainable purchasing, a revised waste reduction and recycling program, “Go Green” tenant education and outreach program and water efficient fixtures and landscaping.

Additionally, the One Overton Park management office is active in the Hines GREEN OFFICE (HinesGO) program. HinesGO is a voluntary, internal program created to measure and reward sustainability within all Hines offices worldwide. Hines recently expanded the GREEN OFFICE program by offering it to its more than 4,000 tenants worldwide.

One Overton Park is 90 percent leased to tenants including: Bennett Thrasher, CBIZ, Corporate Holdings, Gas South and Jamestown.
